So, in theory, mirror lockup makes perfect sense. It stands to reason that getting rid of vibration would cause sharper pictures–especially for longer exposures. But I’ve always felt like it was a conspiracy of the camera manufacturers. I think they got together in some high rise in Japan and decided to put one feature in our cameras that was a complete placebo, and they’ve been laughing about it ever since. ”What fools!” they say, as we tout the placebo and use it religiously so that we can feel like our photos are sharper than the blockhead next to us who hasn’t yet discovered it.
